New research confirms residential PV tends to increase household power consumption
New Swiss research shows PV-powered homes can increase power consumption by up to 11% compared to non-solar households. This rise is linked to electric vehicle adoption or other high-usage appliances, which the study’s author notes is not inherently negative or wasteful.
SERIS achieves world record efficiency of 26.7% for perovskite-organic tandem solar cell
The tandem device is based on a bottom organic cell that can achieve a remarkable power conversion efficiency of 17.9% and a high short-circuit current density of 28.60 mA cm2. Furthermore, it uses a top perovskite solar cell with an open-circuit voltage of 1.37 V and a fill factor of 85.5%.
EU adopts state aid framework for cleantech industry
The European Commission has developed a new state aid framework under the Clean Industrial Solutions Act for Europe (CISAF) to support clean technology manufacturing across the European Union.
New research sheds light on voltage deficit in selenium solar cells
An international research team has investigated the impact of intrinsic point defects in selenium solar cells and has concluded that these defects are not responsible for voltage deficit. The scientists rather believe interfaces and extended defects may be the cause of this well-known issue for this kind of PV device.
French parliament rejects proposal for moratorium on solar, wind
The French National Assembly has rejected an amendment that could have jeopardized the country’s energy transition.
Armenia’s largest solar plant comes online
Spain’s FRV has commissioned a 62 MW solar plant in Armenia under a long-term power purchase agreement (PPA) with Electrical Networks of Armenia CJSC. The project is the country’s biggest operational PV facility to date.
Improving LECO-compatible silver pastes to ensure TOPCon reliabilty
Researchers in China have created new silver pastes for TOPCon solar cell LECO manufacturing. The new pastes integrate either aluminum, gallium or iron and can reportedly keep cells’ electrodes securely anchored to the silicon cell surface due to the enhanced stability of the lead oxide (PbO) component in the glass powder.
Longi, Pertamina plan 1.4 GW solar cell, module factory in Indonesia
Chinese solar manufacturer Longi and Indonesian state-owned energy company Pertamina are planning to build a 1.4 GW solar cell and module production facility in West Java, Indonesia.
